Published Papers

  • Preparation and Characterization of Phenolic Prepolymer Impregnated Chinese Fir by Cyclic Increasing-Pressure Method with Green and Efficient
  • Abstract The Chinese fir wood was impregnated using a cyclic increasingpressure method (CIPM) with phenolic prepolymers as the impregnating modifier. Unmodified Chinese fir and progressive increasing-pressure method (PIPM) impregnated Chinese fir were used as reference samples and were compared and analyzed. The product’s chemical structure, internal morphology, crystal structure, and heat resistance were characterized. The transversal and longitudinal sections showed better filling effects, so that it bore greater external loading and reduced the water storage space. CIPM infused more phenolic prepolymer into the Chinese fir. Not only producing more physical filling but also forming more hydrogen bond associations and chemical bond… More

  • Alleviation of Drought Stress in Wheat Using Exogenous Ulva prolifera Extract Produced by Enzymatic Hydrolysis
  • Abstract Drought is one of the major abiotic stresses that affect plant growth and reduce agricultural productivity. Use of algal extract as a biostimulant is gaining increased attention from researchers. This study aimed to investigate the potential of Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after 120 h of drought stress relative to that in treatment with the negative control. An increase in catalase (CAT) and peroxidase (POD) activity was also observed that resulted in… More

  • Effects of Biochar Particle Size on Methane Emissions from Rice Cultivation
  • Abstract Biochar amendment is generally recognized as an effective mitigation option of methane (CH4) emissions from rice cultivation. Although its mitigation mechanisms are not well understood, the potential relevance of surface area and porosity of biochar has been discussed. This study aimed to evaluate the application of different biochar particle sizes on CH4 production, oxidation, and emissions from rice cultivation in a clay loam soil, based on the assumption that porosity and surface area of biochar are directly related to its mitigation effects. Rice was grown under greenhouse conditions for two growing seasons, either with 0.5–2 mm (small, SB) or with… More

  • Degradation of Spent Radioactive Ion Exchange Resins and Its Mechanisms by Fenton Process
  • Abstract Spent IERs are released during the operation and decommissioning of nuclear facilities. The safe and efficient treatment of spent IERs is an emergent problem in nuclear industry. IRN77 is a typical ion exchange resin widely used in many nuclear power plants. Fenton process can degrade organic resins and reduce the radioactive residues volume and the disposal cost significantly. In this work, the IRN77 resin was selected as a model ion exchange resin and its treatment via Fenton process was investigated. The influencing factors for resin degradation, including catalyst dosage, reaction time, initial pH, temperature and oxidant dosage were investigated and… More

  • Synthesis of Bio-Plasticizer from Soybean Oil and Its Application in Poly(Vinyl Chloride) Films
  • Abstract Herein, epoxidized soybean oil methyl ester (ESOM) plasticizer was synthesized for the preparation of plasticized poly(vinyl chloride) (PVC) films by the alcoholysis and epoxidation. The chemical structure of ESOM was investigated by infrared spectrum and 1H nuclear magnetic resonance. The effect of content of ESOM and petroleum based plasticizer di-2-ethylhexyl phthalate (DEHP) on the performance of plasticized PVC films was studied. The result showed that substituting DEHP with ESOM can improve the thermal stability of plasticized PVC films. When the weight ratio of ESOM and PVC is fixed at 1:2, plasticized PVC film presents higher elongation at break (350.8% vs.… More

  • Interfacial Modification of Corn Stalk Cellulose Reinforced Used Rubber Powder Composites Treated with Coupling Agent
  • Abstract Corn stalk cellulose (CS)/used rubber powder (RP) composites were prepared by mixing, the silane coupling agent 3-Mercaptopropyl trimethoxysilane (KH590), r-Aminopropyltrieth oxysilane (KH550), isopropyl dioleic (dioctylphosphate) titanate (HY101) and bis-(γ-triethoxysilylpropyl)- tetrasulfide (Si69) were used to modify the interface of composites. The effects of the CS and coupling agents on the mechanical properties, thermal properties, interfacial morphology and structure of the composites were investigated, respectively. The results showed that the addition of CS could effectively improve the mechanical properties of the composites. Compared with the untreated composites, the interfacial bonding between CS and RP was significantly improved by the coupling modifi- cation… More

  • Abstract In order to study the effect of recycled plastic particles on the physical and mechanical properties of concrete, recycled plastic concrete with 0, 3%, 5% and 7% content (by weight) was designed. The compressive strength, splitting tensile strength and the change of mass caused by water absorption during curing were measured. The results show that the strength of concrete is increased by adding recycled plastic into concrete. Among them, the compressive strength and the splitting tensile strength of concrete is the best when the plastic content is 5%. With the increase of plastic content, the development speed of early strength… More

  • Synthesis and Interfacial Properties of Bio-Based Zwitterionic Surfactants Derived from Different Fatty Acids in Non-Edible Vegetable Oils
  • Abstract Waste cooking oils and non-edible vegetable oils are abundant and renewable resources for bio-based materials which have showed great potential applications in many industries. In this study, five fatty acids commonly found in non-edible vegetable oils, including palmitic acid, stearic acid, linoleic acid, linolenic acid, ricinoleic acid, and their mixtures, were used to produce bio-based zwitterionic surfactants through a facile and high-yield chemical modification. These surfactants demonstrated excellent surface/interfacial properties with the minimum surface tensions ranging from 28.4 mN/m to 32.8 mN/m in aqueous solutions. The interfacial tensions between crude oil and surfactant solutions were remarkably reduced to lower values… More

  • Sunflower-Like SrCo2S4@f-MWCNTs Hybrid Wrapped by Engineering N-Reduced Graphene Oxide for High Performance Dye-Sensitized Solar Cells
  • Abstract A novel sunflower-like nanocomposite of SrCo2S4 nanoflakes and functionalized multiwall carbon nanotubes (f-MWCNTs) entanglement enveloped in nitrogen-reduced graphene oxide (N-RGO) is prepared by a cheap process. The unique entanglement structure of the material exhibits higher specific surface area, better electrical conductivity and other properties. This helps to reduce the transfer resistance in the photoelectric process of the battery and improve the electrochemical activity, thus increasing the photoelectric conversion efficiency of the battery. The new ternary cobalt-based sulfide material can replace platinum as the counter electrode (CE) material loaded on dye-sensitized solar cells (DSSCs). DSSCs with SrCo2S4@f-MWCNTs@N-RGO (SCS@f-M@N-R) as CE material… More
